KETTERING: Pulmonary Diagnostic Testing (PFT's) Exam with || || || || || || ||
accurate detailed answers || ||
What types of equipment is used for PFT - ✔✔- spirometers (Volume and Flow)
|| || || || || || || || || || || || || ||
- peak flow meter (PEFR) (Flow)
|| || || || ||
- MIP/NIF
||
- MEP
||
Spirometers are used to measure: - ✔✔volumes and flow rates
|| || || || || || || || ||
Peak flow meters are used to measure: - ✔✔peak expiratory flow rate (PEFR) at the bedside
|| || || || || || || || || || || || || || ||
How do you measure PEFR? - ✔✔patient exhales forcefully through a device which
|| || || || || || || || || || || || ||
incorporates a resistor and a moveable indicator || || || || || ||
- fully dependent on patient effort
|| || || || ||
- moisture and debris can affect accuracy
|| || || || || ||
How to determine personal best peak flow number? - ✔✔the single highest measurement
|| || || || || || || || || || || || ||
recorded during this time frame is the personal best
|| || || || || || || ||
Typical peak flow value for a healthy adult? - ✔✔10 L/sec or 600 L/min
|| || || || || || || || || || || || ||
How do you calibrate a 3.0 L syringe? - ✔✔syringe should be calibrated daily
|| || || || || || || || || || || || ||
accuracy within pos. or neg. 3.5% (2.895 L - 3.105 L)
|| || || || || || || || || ||
, MIP/MEP (pressure manometer) device is used for: - ✔✔measurement of maximum
|| || || || || || || || || || ||
pressures. more accurate than vital capacity measurements in pts with neuromuscular
|| || || || || || || || || || ||
disease
how is MIP measured? - ✔✔with a pressure manometer; described in negative numbers
|| || || || || || || || || || || || ||
- used to monitor and assess the readiness to wean in ventilatory patients.
|| || || || || || || || || || || || ||
- also assessed the degree of respiratory muscle impairment in pt with GB and MG
|| || || || || || || || || || || || || ||
What MIP measurement indicates weak muscles? - ✔✔MIP < 20 cmH2O
|| || || || || || || || || ||
how is MEP measured? - ✔✔with a pressure manometer; described in positive numbers
|| || || || || || || || || || || ||
- helpful in evaluating a patients ability to maintain an airway or clear secreting (ability to
|| || || || || || || || || || || || || || || ||
cough)
Spirometry values || ||
a. VT ||
b. IRV ||
c. ERV||
d. RV ||
e. IC ||
f. VC||
